  High pressure hydraulic steel tube   is designed to convey liquid fluids to among hydraulics components, fittings, valves, flanges, and other tools. It is made of material E355 (ST 52.4) or E235 (ST 37.4). These two grades have different chemical composition. This helps to control the working pressure.  The hydraulic steel tube is cylinder-like shaped tubing device that when attach to hydraulic systems, allow for the passage of fluids within and among components. The tube standard specifies dimensions for cold drawn finishing and ​ seamless precision steel tubes . Cold drawn process provides the hydraulic steel tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic steel tubes are suitable in high performance piping system application.  There are two type of material grade for high pressure hydraulic steel tube, ST52.4 and ST37.4.   ST52.4 is high tensile strength tube means ...

 The hydraulic steel tube is cylinder-like shaped tubing device that when attach to hydraulic systems, allow for the passage of fluids within and among components. The tube standard specifies dimensions for cold drawn finishing and ​seamless precision steel tubes. Cold drawn process provides the tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic tubes are suitable in high performance piping system application. Hydraulic steel tube is basically divided into the hydraulic system with fluid pipe and oil cylinder, also known as honing tube, and cold drawn or cold rolled precision seamless steel pipe also contains hydraulic tube. Hydraulic pipe after finishing, no oxidation bright heat treatment of raw materials (NBK), nondestructive testing, steel pipe inner hole through high pressure washing, pickling, block on both ends of the steel tube inside and outside wall with anti-rust oil antirust proce...
